Mob ncauj tsev me nyuam MRI

Daim duab thaij duab MRI ntawm lub ncauj tsev menyuam (siv lub zog loj) los tsom lub zog siv los ntawm cov hlau nplaum muaj zog los tsim cov duab ntawm ib feem ntawm tus nqaj qaum uas khiav los ntawm caj dab thaj (caj dab txha nqaj qaum).

MRI tsis siv duab hluav taws xob (x-ray).

Ib leeg MRI cov duab yog hu ua cov hlais. Cov duab tuaj yeem khaws cia rau hauv computer lossis luam tawm ntawm zaj duab xis. Ib qho kev kuaj xyuas tsim tau ntau cov duab.

Koj yuav tau hnav khaub ncaws hauv tsev kho mob lossis khaub ncaws yam tsis muaj xaim hlau lossis txeeb khoom noj (xws li cov hws lossis lub tsho loj). Nco ntsoov tias koj hle koj lub moos, cov hniav nyiaj hniav kub thiab hnab nyiaj. Qee hom hlau tuaj yeem ua rau cov duab tsaus muag.

Koj yuav tau pw saum lub rooj nqaim uas zawv zawg mus rau hauv lub voos xwm kab.

Qee qhov kev ntsuam xyuas siv cov zas xim tshwj xeeb (sib piv). Yuav luag txhua lub sijhawm, koj yuav tau txais qhov zas xim los ntawm txoj hlab ntsha hauv koj txhais tes lossis sab tes ua ntej ntsuas. Cov xim tuaj yeem muab tau los ntawm kev txhaj tshuaj. Zas yuav pab cov kws ntsuas hluav taws xob pom qee thaj chaw kom pom tseeb.

Thaum lub sij hawm MRI, tus neeg siv lub tshuab yuav saib xyuas koj los ntawm lwm chav. Qhov kev kuaj mob feem ntau kav 30 mus rau 60 feeb, tab sis yuav siv sijhawm ntev dua.

Koj yuav raug hais kom tsis txhob noj lossis haus dab tsi rau 4 rau 6 teev ua ntej kev thaij.

Qhia koj tus kws kho mob yog tias koj ntshai qhov chaw kaw (muaj claustrophobia). Koj yuav tau muab tshuaj kom pab koj tsaug zog thiab tsis ntxhov siab. Koj tus kws kho mob yuav qhia ib qho MRI "qhib", hauv lub tshuab kom tsis ze ntawm lub cev.

Ua ntej sim, qhia rau koj tus kws kho mob yog tias koj muaj:

• Hlwb aneurysm txiav
• Qee yam ntawm cov khoom cua plawv tus kheej
• Lub plawv defibrillator los yog ua pa nplawm
• Pob ntseg hauv (cochlear) kev cog hniav hauv
• Kab mob hauv lub raum lossis lim ntshav (tej zaum koj yuav tsis tuaj yeem txais kev sib piv)
• Nyuam qhuav tso cov pob qij txha txuas
• Qee hom vascular stents
• Ua haujlwm nrog ntawv hlau yav dhau los (tej zaum koj yuav xav tau kev ntsuam xyuas los kuaj xyuas cov ntawv hlau hauv koj lub qhov muag)

Vim tias MRI muaj cov hlau nplaum muaj zog, cov khoom hlau tsis pub nkag mus rau hauv chav tsev nrog MRI scanner:

• Cwjmem, hnab looj tes, thiab tsom iav yuav ya hla chav.
• Cov khoom xws li cov hniav nyiaj hniav kub, watches, credit card, thiab khoom siv tau hnov ​​tau ua kom puas ntsoog.
• Pins, hairpins, hlau zippers, thiab cov khoom siv hlau zoo ib yam tuaj yeem cuam tshuam cov duab.
• Kev tshem hniav ua haujlwm yuav tsum tau coj tawm ua ntej lub scan xwb.

Kev kuaj MRI ua rau tsis muaj mob. Koj yuav tau dag tseem. Ntau dhau ntawm lub zog tuaj yeem plooj MRI cov duab thiab ua rau tsis raug.

Lub rooj yuav tawv lossis txias, tab sis koj tuaj yeem thov kom pam vov lossis pam vov. Lub tshuab ua suab nrov nrov nrov thiab ua kom nrov nrov thaum muab tua. Koj tuaj yeem hnav lub pob ntseg ua kom pab tiv thaiv lub suab nrov.

Lub intercom nyob rau hauv chav tsev tso cai rau koj mus hais lus rau ib tug neeg thaum twg los tau. Qee tus MRI muaj cov TV thiab lub mloog pob ntseg tshwj xeeb los pab lub sijhawm.

Tsis muaj lub sijhawm rov zoo li, tsuas yog koj tau muab tshuaj rau kom ib ce ntaug. Tom qab kuaj MRI, koj tuaj yeem rov qab mus rau koj li qub noj haus, ua si, thiab tshuaj.

Cov laj thawj feem ntau rau qhov kev xeem no yog:

• Kev mob caj dab, xwb pwg, lossis caj npab uas tsis mob zoo dua tom qab kho tas
• Mob caj dab nrog rau txhais ceg tsis muaj zog, loog, lossis lwm yam tsos mob

Yuav kuaj MRI rau lub tsev me nyuam.

• Kev yug los ntawm caj qaum
• Kab mob uas koom nrog koj tus txha caj qaum
• Mob los yog raug mob rau tus txha nqaj
• Ntau yam sclerosis
• Scoliosis loj heev
• Mob qog nqaij hlav lossis mob qog ntsha nraub qaum
• Mob pob txaws hauv nqaj qaum

MRI ua haujlwm tau zoo dua ntawm CT scan hauv kev txheeb xyuas cov teeb meem no feem ntau.

Lub ncauj tsev me nyuam MRI kuj tseem yuav ua tau ua ntej kev phais mob txha caj qaum.

Ib qho txiaj ntsig uas ua tau txhais tau hais tias feem ntawm txha nraub qaum uas khiav los ntawm koj lub caj dab thiab cov leeg nyob ze ze tau zoo li qub.

Cov laj thawj feem ntau ua rau muaj qhov txawv txav yog:

• Herniated lossis "plam" disk (caws mos radiculopathy)
• Qhov nqaim ntawm lub ncauj tsev menyuam txha nqaj qaum (txha nqaj qaum)
• Kev coj txawv txav ntawm cov pob txha thiab pob txha mos hauv caj dab (caws mos txha nqaj qaum)

Cov txiaj ntsig tsis meej kuj tseem yog vim:

• Kev hloov pauv hloov vim lub hnub nyoog
• Kab mob pob txha (osteomyelitis)
• Disk o (diskitis)
• Kev kis mob ntawm tus txha nqaj qaum
• Ntau yam sclerosis
• Tus txha nqaj qaum lossis mob nraub qaum
• Pob txha txha caj qaum
• Cov pob txha caj qaum

Tham nrog koj tus kws kho mob txog koj cov lus nug thiab kev txhawj xeeb.

MRI tsis muaj hluav taws xob. Kuj tsis muaj xov xwm tshwm sim los ntawm cov kev sib nqus thiab xov tooj cua loj.

Nws tseem muaj kev nyab xeeb uas tau MRI ua thaum cev xeeb tub. Tsis muaj kev mob tshwm sim los sis cov kev mob tshwm sim tau pom.

Qhov feem ntau ntawm cov sib piv (zas xim) siv yog gadolinium. Nws muaj kev nyab xeeb heev. Kev fab tshuaj rau qhov muaj cov khoom tsis tshua muaj. Txawm li cas los xij, gadolinium tuaj yeem tsim kev puas tsuaj rau cov neeg uas muaj teeb meem lub raum uas xav tau lim ntshav. Yog tias koj muaj teeb meem lub raum, thov qhia koj tus kws kho mob ua ntej kuaj.

Lub teb muaj zog sib nqus tsim thaum lub sij hawm MRI tuaj yeem ua rau lub plawv ceev thiab lwm yam kev cog hniav tsis ua hauj lwm zoo li. Nws kuj tseem tuaj yeem ua rau ib daig hlau nyob hauv koj lub cev txav lossis hloov. Vim kev nyab xeeb, thov tsis txhob nqa ib yam dab tsi uas muaj hlau rau hauv chav ntsuas scanner.
